ActionBar not working

Question

I need some guidance regarding the working of Action bar. Actually clicking on a Action bar MenuItem. Current activity must be moved to another activity. But it's doing nothing. Not even any error. I used following code:

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.mnew1, menu);
    return super.onCreateOptionsMenu(menu);
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle presses on the action bar items
    switch (item.getItemId()) {
        case R.id.home:
            try {
                openSearch();
            } catch (IOException e) {
                e.printStackTrace();
            }
            return true;
        default:
            return super.onOptionsItemSelected(item);
        }
    }

private void openSearch() throws IOException{
    val=address(location.getLatitude(), location.getLongitude());
    Intent intnt=new Intent(getApplicationContext(),SendSms.class);
    intnt.putExtra("loct", val);
    startActivity(intnt); 
}

clicking on which action bar button? – Paresh Mayani Dec 16 '13 at 06:06 — Paresh Mayani, Dec 16 '13 at 06:06
means you have taken one item with R.id.home id? – Paresh Mayani Dec 16 '13 at 06:44 — Paresh Mayani, Dec 16 '13 at 06:44

Use MenuInflater inflater = getSupportMenuInflater();

And if you are using android home button then the id is android.R.id.home. In that case make sure you have getSupportActionBar().setDisplayHomeAsUpEnabled(true); in your onCreate.

EDIT- Make sure you have imported these:

import com.actionbarsherlock.app.ActionBar;
import com.actionbarsherlock.view.MenuItem;

It's simple. Remove all your imports. Then press ctrl+shift+o. – Naddy Dec 16 '13 at 06:16
@user3101598 Hey, are you using ActionBarSherlock in the first place? – Naddy Dec 16 '13 at 06:29
i didn't get what are you trying to say – user3101598 Dec 16 '13 at 07:14
Post your whole `Activity` and `mnew1.xml`. – Naddy Dec 16 '13 at 08:45
just answer a simple question is it possible to get current location in one activity and passing address from there to another activity – user3101598 Dec 16 '13 at 15:55
Yes, it is possible. You may want to explain what does `val=address(location.getLatitude(), location.getLongitude());` do? – Naddy Dec 16 '13 at 17:29
i have pasted my full code at with few modification..please have a look..http://stackoverflow.com/questions/20609847/current-location-from-latitude-and-longitude noredirect=1#comment30852843_20609847 – user3101598 Dec 16 '13 at 17:55

put this code inside onCreate method:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.your_main_activity_xml);

    // creating Actionbar
    ActionBar actionBar = getActionBar();
    actionBar.setHomeButtonEnabled(true);
    actionBar.setDisplayHomeAsUpEnabled(true);
    actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_STANDARD);
    actionBar.setBackgroundDrawable(new ColorDrawable(Color.BLUE));
    actionBar.setDisplayShowTitleEnabled(true);
    actionBar.show();
    ...

}

and then put this code outside onCreate :

@Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.mnew1, menu);
return super.onCreateOptionsMenu(menu);
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle presses on the action bar items
switch (item.getItemId()) {
    case R.id.home:
        try {
            openSearch();
        } catch (IOException e) {
            e.printStackTrace();
        }
        return true;
    default:
        return super.onOptionsItemSelected(item);
    }
}

private void openSearch() throws IOException{
val=address(location.getLatitude(), location.getLongitude());
Intent intnt=new Intent(getApplicationContext(),SendSms.class);
intnt.putExtra("loct", val);
startActivity(intnt); 
}

this code is perfect. There is not any problem with this code. Actionbar button was not working due to null value it is receiving..and null value was just because of some hardware issues..nothing wrong with this code thanks
